About Trigger

• Trigger is setup to run a pipeline automatically
• We can configure a pipeline to run upon a push to a repository, at scheduled times, or upon the completion of another build
• Trigger types:
  • CI trigger or Push trigger
  • PR trigger or Pull request trigger
  • Scheduled trigger
  • Pipeline completion trigger

CI trigger with list of branch names

azure-pipelines.yml

trigger:
- main
- dev
- feature

CI trigger with complete control

  branches:
    include:

Disable CI trigger

First, disable “Override YAML continuous integration trigger”

• Pipelines > All > select the target pipeline
• Edit > Click on more options (virtical dots on top right) > Trigger
• Unheck “Override the YAML continuous integration trigger from here”
• Save

Now, disable CI trigger in yaml: azure-pipelines.yml

# A pipeline with no CI trigger
trigger: none

# ... ... ...

Notes:

• For multiple pipelines with multiple yaml files, repeat the process decribed above for all pipelines
• Add trigger: none to all yaml files
